  • I NEED ALOT OF HELP!!! 97 firebird v6

    so heres the deal. ive owned my 1997 pontiac firebird for over a year now and i have done alot to it over the year and ran into alot of problems. i have alot of questions, and all the guys on these forums are real helpful, so please give me a hand. ill put the questions in order so itll be easier to answer me back by. also we will have another fbody member soon since im handing my fireibird down to soon 16 year old brother. thanks for looking guys.

    specs: 1997 pontiac firebird 3.8l v6. flowmaster 80 series, no cadillac converter. CAI. 3200 watt stereo system.


    questions:

    #1. my car had cooling problems and need the water pump redone when i first got it. i had a mechanic i trust put the ac delco water pump on and it wasnt leaking coolant anymore. around the same time i put a cheap ebay cold air intake CAi on the car. so after a while of driving i noticed the car would heat up at stop lights and when i was just driving around the city. ive done the raditor flush, put a 180 thermostat in, and switched out the temperature sending unit, the wires also dont look mangled from the temp sending unit. i was wondering if you have any other solutions or something i could try out. on highway it stays at 180 around city it jumps up to 200. its been above 210 once or twice. normally jumps up to about 200 at a stoplight. please give me any advice that may have worked for you.

    #2. my voltage varies every now and then. mostly around 14 volts all the time but i put a big sound system in it. it drops alot when i bump that is to be expected. once or twice a week with nothing on it will be barely at 12 volts. i plan on doing the big three to help the voltage. the altenator may be bad but my battery tester says the battery is fine. i still gotta check the altenator. let me know if there is any possible solutions for this also.

    #3. does my electrical system have anything to do with my temperature readings going haywire.

    #4. also when i put my redefrost on the electrical voltage drops 2 volts down to about 12 volts sometimes when it is being crazy.

    those are my main concerns right now. thanks for looking.

    on a side note i plan on getting a newer trans am or camaro since the cost of them. should i look into an lt1 or ls1. i think i want an ls1 camaro z28. i plan on doing alot of engine work but i am gonna try something that is mostly modded and finished but not ran hard. just let me know cost wise and dependablitiy of which engine is better to buy because i can get a car with a lt1 cheaper than a ls1 engine.

    #1. Sounds like a fan issue. Check/replace your two fan relays ... or you can get one of those fan switches, so you can turn them on if you'll be sitting for long at idle.
    #2. Your voltage problem may be fixed with something as simple as a large capasitor or a second battery (just for the amps)
    #3. Not unless the temp. sensors/fan relays/fan wiring are bad.

      Your voltage problem could be bad, corroded, of loose grd connection. The amp is my main suspect you probably are drawing more current than altenator can put out. a high capacity capacitor will give it some help, but you probably need to change alt to a 120 or 150 amp. I think v6 is a 80 amp alt.
      When you can not deliver the current necessary for the draw of whats on it will pull the voltage down.

      Cooling issue sounds like your fan control sensor is bad or your fan motors are bad. Start your car and let it idle and reach temp. around 180 you should hear fans kick on. If this is all working OK then I would check the pressure on your cooling system. A bad radiator cap or a small leak some where can cause lower pressure and cooling issues.
